PUMP OILER.

Application tiled September 13, 1922. Serial No. 587,975.

To all whom t may concern.

Be it known that I, ERNEST R. SrMoNs, a citizen of the Dominion ofCanada, and a resident of Wapella, in the Province of Saskatchewan,Canada, have invented a new and Improved Pump Oiler, of which thefollowing is a full, clear, and exact description.

Thisinvention relates to improvements 1n pump oilers, andmgreparticularly to an improved oil cari from which the oil can bepumped'in any quantity and with the force desired, so as to inject theoil wherever needed, an object of the invention being to provide adevice of the character stated in which a slight pressure of the thumbon the lever will function toeject the oil from the dev construction andarrangement of thumb lever.

operating mechanism which is convenient to operate with either handwhile wearing ay mitt or glove.

A further object is to provide a device of the character stated, whichcan be easily and completely taken apart for cleansing or 1ns ection ina relatively short time and readi y assembled again for use.

With these and other objects in View, the invention consists incertainnovel features of construction and combinations, and arrangement ofparts, as will be more fully hereinafter described and pointed out 1nthe claims.

In the accompanying drawings- Figure 1 is a view in longitudinal sectionillustrating my improved pump oiler.

Fi ure 2 is aview in transverse section on the line 2 2, of Figure 1.

Figure 3 is a fragmentary view in longitudinal section showing-theplunger in its lower position. l

1 represents an oil container having a handle 2 at one side, andprovided with a screw threaded nipple 3 at its upper end through whichthe oil can be supplied to the container. Within this nipple 3 a pumpcylinder 4 snugly lits, and projects into the container 1. This cylinder4 has an annular flange 5 adjacent its upper end, and a union 6 engagesover the flange 5 and is screwed onto the nipple 3 securing the cylinderin place and operating as a closure for the container, but permittingsaid parts to be readily taken apart as may be'desired.

At the lower end of the cylinder 4 the same is provided with a threadedboss 10 to which is attached a reduced inlet chamber 7 whichcommunicates at its lower end with an inlet tube 8 having a screenedlower end 9 adja-l cent the bottom of container 1. A coiled spring 11 islocated in the chamber 7 and interposed between the boss 10 and a ballvalve 11 which normally closes the opening 12 connecting tube 8 with thebottom of chamber 7.

A plunger bodv 13 fits the cylinder 4, and at its lower end is providedwith a plunger 14 including the plunger leathers 14 and having a centralremovable tube 15 constituting an oil passage and acting as a couplingmeans between the sections of the plunger to hold the parts thereoftogether. This tube 15 communicates with an outlet chamber 16 to whichlatter an outlet tube 17 is connected and constitutes a spout.

The outer end of the spout 17 carries a conical casing 18 which hasscrew threaded engagement with a truncated conical casing section 19,the latter overlapping the upper end of plunger body 13 and preferablysoldered, or otherwise secured thereto.

In the outlet chamber 16, a ball check 2O is provided normally closingthe upper end of tube 15 and held in normal position by a coiled spring21. On the upper outer end of the cylinder 4 a drip pan 22 is rigidlyfixed, and is provided at one end with an angular link 23 which isengaged by my imvproved thumb lever 24. This thumb lever 24 ispreferably composed of strong wire of general fork shape having itsintermediate portion straddling the section 19 and engaging fingers orpins 25 projecting from opposite sides of the latter.

The ends of the wire are bent forming hooks 26 which engage the link 23so that the latter constitutes a fulcrum for the movement of the lever.The free end of the lever 24 is located above the handle 2 in convenientposition to be engaged by theathumb of the operator, and a guide link 27is fixed to the container 1 and permits operation of handle 2 with onehand and with the thumb of the same hand exerts a downward pressure onthe free end of lever 24. This causes a downward movement of the entireplunger body and plunger 14, which forces the oil between the checkvalves 20 and 11, upwardly, anda spring 28 located below the 'plunger 14compels the plunger to move upwardly when pressure is relieved on thelever 24. This upward and downward movement'of the plunger will ejectthe oil as rapidly and with the force desired so that the container canbe held in vertical position or in any ordinary position and forcethe'oil Wherever desired.

Various slight changes might be made in the general form andlarrangement of parts described without departing from my invention, andhence I do not limit myself to the precise details set forth, butconsider myself at liberty to make such changes and alterations asfairly fall within the spirit and scope of the appended claims.

I claim:

1. A pump oiler, comprising a container, a handle-on the container, apump cylinder removably secured in the container, a pump plunger movablein the cylinder and having an oil guiding portion projecting'out of thecylinder, check valves in the c linder, and plun er controlling the flowo oil, a drip pan xed to the cylinder outside of the container, a linkon the drip pan, a thumb lever fulcrumed to the link and at itsintermediate portion engaging the body portion of the plunger and havingits free end located yadjacent to said handle.

Y A2. V1Lfpump oiler, comprising a container hivingga screwthreadednipple'at its upper end, a pump cylinder projected through thenipple and having an annular flange engaging the nipple, a union screwedinto the inipple and securing the cylinder in the conl jecting outsideof the same, a plunger body fitting the cylinder, a plunger on the lowerend of the plunger body, a coupling tube coupling the parts of theplunger together and providing an oil passage therethrough, a tubelocated within the plunger body and projecting beyond the same andcommunieating with said passage, a spring in the cylinder exertingupward pressure on the plunger, a thumb lever for forcing the plungerdownwardly, a reduced chamber at the lower end of the cylinder andcommunieating therewith, and check valves for closing. said firstmentioned passage and the inlet to said last mentioned chamber.

4. A pump oiler, comprisino a container, a pump in the container, a drlppan having xed relation to the container, a link on the drip pan, a wirelever straddling the pump andhaving hooked ends engaglng the link, meanson the container limiting the movement of the lever in one direction,and a handle on the container located in lclose proximit to the free endof the lever.
